If the merchant prefers to add a credit card on file for gateway billing, please follow the steps listed below.
- The merchant or ISO may request this by calling our support number: 847-352-4850 ext. 1.
- They can also send an email to support@nmi.com with the merchant's business and gateway ID.
-In the body of the email, please clarify that you would like to have the flag enabled that will allow the partner and the merchant to add a credit card on file for gateway billing. Once we receive the email, we will enable it on our end and confirm with you via email.
Once this flag has been enabled, you can log into your affiliate portal to add the credit card information under 'Default Merchant Bank Information (For Billing).'
The merchant can also add a credit card by logging into their gateway account >> click options >> click settings >> click 'Account Information' and they should be able to add the credit card information.
***Please note: If the merchant's banking information is on file and they also have their credit card on file, the credit card will always override the banking information. This means that their gateway fees will be charged on their credit card even though they have their banking information on file.
